Problem with using the key-on method is there is some timer built into the system that doesn't allow the fuel pump to run if you try it a second time. I don't know the length of time before it allows the pump to run again with another key-on...

If anyone has the technical knowledge to tell me how to power up the tank fuel pump to prime the fuel rails after hi-pres pump replacement and injector work (don't need to know to turn on the key for for priming, as that only runs the pump for a few seconds). Old days, used to be able to power, jumper, at the fuel pump relay, but that does not work with these new vehicles. Its a 2014 Silverado w/ 5.3 and automatic. The key-on prime is not long enough to get it fully primed and pressurized. Is there an easy way to give the fuel pump some power? Key word - easy. Thank you.

OK, here's my situation. In the past, I have seen GM Customer Care agents answering comments on this forum. I'm hoping they or someone involved with a dealer can answer this? I have a 2014 Silverado K1500 LT, 5.3, automatic. I have been looking at GM service documents on fuel odors, and 13331 in particular. It states in that document that certain 2014 models had a 'misbuilt' SIDI high pressure fuel pump. And that any vehicle that was in for any service during the warranty period was to be verified for this bad pump: "All involved vehicles are identified by VIN in the Global Warranty Management System – Investigate Vehicle History Application. Dealership technicians should always check this site to confirm vehicle involvement prior to beginning any required inspections and/or repairs." They were to verify this before any work the vehicle was brought in for was to be started. I am curious whether my vehicle ever was verified, as it appears in the document that it's up to the technician to do this. I was never told that anything like this was verified. And I did complain about the very loud ticking sound, which they said it was the fuel pump and that it was normal. So does mine fall in the group that by VIN would have told them the high pressure fuel pump should have been replaced? I am seeing in the forums also that people that have had the pumps replaced, that it reduced the ticking sounds down to almost nothing. I can provide a VIN...

I found where the mice got into mine and this was my fix. Haven't had a mouse in the cabin filter since.

Since I have put in the folded up window screens in the gaps at the ends of the plastic cowl, I have not had a mouse get into the hvac and cabin filter system. So much for the naysayers saying they'll just chew thru it and to just live with nature...

yep...all owners want is a reasonable effort of engineering to keep mice out. That being said, we all know they will still get under the hood and possibly create problems there. But I'd rather not have them building nests in top of the cabin filter, pissing and defecating on it, then those smells and possibly diseases and viruses being fanned into the cab of the vehicle. That being said, some people are ok with mice living in their house also. Gross. I don't believe any ever got into my home as a result of the home builder's actions.Might have had a mouse one time years ago, and probably got in when a door was open. It had a short life...

I'm sure GM must have realized that if mice are getting access to a vehicle, and one runs around in the vehicle while a mouse-phobic person is driving down a freeway at 80 mph, that would be a huge concern legally for GM...

Those saying GM has no responsibility have kind of been shut down by GM...I looked at a 2018 model and I see GM has fixed the problem of the gaps at the end of the cowls. Apparently they do feel it is their responsibility to some degree to make them mouse proof. And it is not food being left in the vehicles either. They enter as in my case when there is no food, they bring their own. They are looking for safe dry places to build their nests...

Sounds like we have a lot of inner city people responding where there are only rat problems and are too big to get into the vehicles...lol. What I ended up doing was removing the plastic cowl, taking fiber-type window screen, rolling it up not really tight, drilling some small holes, and ty-rapping to the ends of the cowl. You have to study the setup to determine length to use. And , really, there are not a 'lot' of places where mice can get into a vehicle. Only a few that could be remedied by the manufacturer during their engineering process, and very easily. With the plastic cowl, they could make the end of it so that it goes all the way down to the body sheet metal. Maybe 1" x 5" or less on either side. And make the gap at the rear corners of the body just wide enough for water to drain and not HUGE enough for mice to get in. Both pretty simple if engineers use their heads. This posting was really meant to help those that do unfortunately have mice in their vehicles and are looking for the access points...do we want to go down a road where we could say that everything can fail and the manufacturer should have no responsibilities for anything?

Apparently GM engineering does not consider mice a problem when their trucks are engineered. Some people have said in different forums that mice getting access is not the manufacture's issue to worry about. You know what I say to that statement... There are two points mice get access. One of the mouse access locations to get into the cab heat/air intake system is the cowl at the bottom of the windshield (2014-18 and maybe other years). They get in at a gap at either side of the cowl right next to the hood hinges. This has a wide gap. Then they go all the way in, to the top of the cabin filter in the vehicle and build their nest. I would suggest filling those cowl gaps with maybe something like a plastic mesh scouring pad cut to size, or something similar. The issue seem to be when you have the ventilation to 'fresh air', thus the fresh air door is open between the firewall and the heating duct system. Some have said to put it in 'recirculate' to close that door, but I don't believe it's the owner's duty to have to remember to do that every time they park the vehicle. I like constant fresh air into my vehicles. Any other suggestions for this are welcome. The other location mice have gained access to the inside of the cab of the vehicle are gaps at the very back corners of the cab at the bottom. I believe they only can access these if you have step bars, or the side steps. I have used folded galvanized window screen cut to size and fitted in these gaps. Never had a problem after that. They may be drain holes, so don't do anything to tightly plug them. These gaps have been on GM truck for many years. I hope this helps those with mice problems.
